Turkey’s state-run news agency said Kurdish rebels have attacked a government building in southeast Turkey with rocket launchers, wounding three people including a district governor.

The Anadolu Agency said rebels of the outlawed Kurdistan Workers’ Party, or PKK, attacked the district governor’s office in the town of Derik on Thursday. Haber Turk television said the district governor, Fatih Safiturk, was slightly wounded in the attack.

A fragile peace process between the state and the PKK broke down in 2015, leading to renewed violence in Turkey’s mainly-Kurdish southeast region. At least 700 state security personnel and thousands of Kurdish militants have been killed since then.

Turkey has been rocked by a series of deadly bomb attacks in the past 18 months, carried out by the PKK or Islamic State group extremists.
